Application filed November 21, 1914. Serial No. 873,372.

To all whom it may concern:

Be it known that I, VAssIL Cor: STANTINE, a citizen 'of the UnitedStates, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented new and useful Improvements inPhonograplrStops, of which the following is a' specification.

The invention relates to phonographs, and has for an object to providean auto matic stop therefor.

The invention contemplates, among other features, the provision of asimple device that can be readily applied to the various In the furtherdisclosure of the invention 4 reference is to be had to the accompanylngdrawings, constituting a part ofthis specification, in which similarcharacters of reference denote corresponding parts in all the views, andin which:

Figure 1 is a fragmentary plan view of a phonograph" showing my deviceapplied thereto, the full lines showing? the tone arm in its finalposition and the dotted lines in playing position; Fig. 2 is an enlargedvertical sectional view taken on the line 2-2 in Fig. 1; Fig. 3 is afragmentary perspective view of a detail portion of the device; and Fig.4: is a vertical sectional view taken on the line etl of Fig. 1.

Referring more particularly to the views, I disclose a phonograph ortalking machine 10 having the usual tone arm 11 mounted to swinghorizontally thereon and operate upon a record 12 carried by a table 13.rev 'oluble by suitable mechanism forming part of the talking machineand whereby rotation is imparted to the record so that a stylus '14 onthe tone arm operating from the outer. edge of the record toward theinner edge thereof will travel in the grooves of the record to producethe sounds in the usual manner.

r A casing 15 supported on the top of the talking machine 10 andarranged to slide through the said casing has a stop member 16 adaptedtohave its inner end engage the table "13, said stop member being actuatedby a spring 17 contained'in the casing 15 and having its other endtermmatmg n a suitable hook 18, an operating lever 19 being pivoted uponthe top of the talking machine 1'0 through the medium of a pin' and slotconnection 20 having connection with the stop member 16 as shown. 1

A sleeve 211s supported on.th e top of the talking machineand'mount'edto slide therein is a rod 22 having itsinner .end pivoted toa bell crank lever 23 mounted to swing upon suitable bearings 24: andhaving an arm 25 thereof terminating in a hook 26 for engagement withthe h0ok-18'on the stop member 16, as shown in Fig 3.

The free end'of the'rod 22 carries an ad justable tubular member v27which is arranged to slide upon the rod and can be secured rigidlythereon by a suitable set screw 2d, said adjustabletubular member 27having its free end provided with a suitable head 29, the face of whichis curved to conform to the curvature of the tone arm 11.

In the operation of-the device, we will assume that the stop member 16engages'the periphery of the table, due to the action of the spring 17,the hook 19 at this time being out of engagement with the hook 26. Thedesired record'having been placed upon the table the tone arm'is nowswung inwardly until the, stylus 1 1 lies in the innermost groove of therecord and when inthisposi tion the tubular member 27 is advanced or.retreatcd'upon the rod until the head 29 of the member-27 abuts againstthe face of the tone arm. The member-27 is now secured rigidly upon therod 22 by the set screw 28 and the tone armis now. swung outwardly untilthe stylus 14 operates in the first or initial groove of the record. Nowby operating the lever 19 the stop member 16 will be moved out ofengagement with the periphery of the-table and in so doing the hook 1!)will he engaged with the hook 26, it being readily seen by referring tothe views that the arm 25 of the bell crank lever 23 extends at an angleto the other arm of the bell crank lever so that-the action ofthe spring17 will not tend to exert a pull upon the rod 22. The table being now inoperation, the tone arm 11 will swing inwardly the stylus 11 advances inthe grooves of the record and when the stylus reaches the inner groove,'it will be clearly seen that the tone arm will engage the head .29 ofthe member 27, thus exerting a push upon the rod22 and r 23 to he swung16% and result in-the .zoolz; with the hool: stop zn'emher 16, so to theaction-of the the table and stop l seription it will be e ouvieedescribed is of a tien consists of few parts cheaply manufactured andreadily ap'glied to machines or (1 my invention, 3'

posed bell crank lever-pivoted to swing upon 26 the phonograph, a hookformed on one arm of the bell crank lever at right angles thereto, a.bearing spaced from the bell crank lever and having a guide sleeve, anadjustable rod pivotally connected to the other 25 In testimony whereofI alhx my signature in presence of two WltIlGS'SQS.
